heinrich5991 9454dfbff9 Remove superfluous parameter from CServer::NewClientNoAuthCallback
The `Reset` parameter was only ever set to true, at the only call site.

heinrich5991 6247aa0c7f Enable -Wextra and -Wformat=2
Also annotate `dbg_msg`, `str_format` and `str_timestamp_ex` so that the
compiler can determine whether the format strings are correct.

Fix the compiler warnings generated by these extra warnings -- some of
them were security issues.

heinrich5991 1d81d56850 Introduce new, vanilla-compatible server info protocol
This means that we have a reliable and fast way to query for extended info,
while also not wasting network bandwidth.

The protocol is designed to be extensible, there's four bytes space for
encoding more request types (currently zeroed), and there's one string in each
response packet and one string for each player available (currently the empty
string).

The protocol itself has no problems with more than 64 players, although the
current client implementation will drop the player info after the 64th player,
because it uses a static array for storage.

Also fixes #130, the player list is just sorted each time new player info
arrives.

Dennis Felsing 45bf601570 Merge pull request #495 from heinrich5991/pr_ddnet_smaller_dummy_map
Reduce dummy map size from 549 bytes to 191 bytes

heinrich5991 0244640aca Also don't send the token magic to unsupported clients
Since only the client can initiate the secure session, there's basically
no reason to send this magic to clients which didn't advertise the
feature.

heinrich5991 702ed7e023 Reduce dummy map size from 549 bytes to 191 bytes
Also include a tool to generate said map; the map is generated without
any hacks. It could likely be made smaller using a few tricks.
